In January 2015, I updated the 2011 World Divorce Rate data and created this figure to illustrate the overall divorce rates. This represents the most current data across the world that is consistently reported to the United Nations. Many countries that have not yet reported 2012 or 2013 data such as the United States and Great Britain are included in this figure. Also, there are 70 countries that have reported their 2012 divorce rates and 11 countries that have reported 2013 data. The original data can be found in the United Nations Demographic Yearbook.
Philip N. Cohen, a sociologist at the University of Maryland, has developed an excellent blog, Family Inequality, in which he discusses a variety of inequality issues. He recently published a paper that explore the impact of the recession on divorce rates. (also discussed in this blog).
You can see more of his thoughts and analysis of divorce issues.
